Rotating Sling PsychroMeter

The sling psychrometer measures air humidity by utilizing the temperature difference between a wet-bulb and a dry-bulb thermometer, combined with airflow generated through rotation, which applies the principle of evaporative cooling. It is used for rapid on-site environmental humidity detection and is commonly found in locations such as warehouses and workshops.
Selection
When selecting based on the measurement range, choose a range of -10~50℃ for conventional environments; check the integrity of the double-ball gauze; prioritize corrosion-resistant models with an aluminum alloy casing; verify the temperature division value, with 1℃ division being suitable for general applications; ensure the rotating mechanism operates smoothly without jamming.
